Fish] BY ATTORNEY United States Patent 3,448,537 CALENDAR Wilmar Lewis Prescott, 5361 Russell Ave., Hollywood, Calif. 90028 Filed July 19, 1967, Ser. No. 654,628 Int. Cl. G09d 3/06, 3/10; G09f 11/04 US. Cl. 40-106 4 Claims ABSTRACT OF THE DISCLOSURE An object of the invention is to provide a calendar of twelve months and a day indicator movable between the turns of the helix to progressively indicate the days and the dates of different months.

A further object is to provide a compact calendar of helical form which is attractive in appearance, inexpensive in cost of manufacture, will readily indicate the day of any month or future months when the day and the date of any month is known, does not require skill to operate the same and which may be small in size and yet wherein the notations carried thereby may be readily readable.

In the drawing:

FIGURE 1 is a side elevation of the calendar;

FIGURE 2 is a top plan view of the calendar of FIG- URE 1 looking in the direction of the arrow 2;

FIGURE 3 is a fragmentary, enlarged view of a portion of one of the turns of the helix, and on an enlarged scale;

FIGURE 4 is a front perspective view of the day indicator with lettering appearing thereon;

FIGURE 5 is a top plan view of the day indicator shown in FIGURE 4;

FIGURE 6 is an enlarged, fragmentary, partially sectional view taken on the line 6-6 of FIGURE 3; and,

FIGURE 7 is a fragmentary, enlarged view of the final turns of the helix.

Referring now to the drawing, the calendar of the invention is shown as an entirety in FIGURE land wherein is provided a base member 1 which supports a helical coil 2 comprising in the present instance a coil having thirteen turns. The angle of the turns relative to the plane of the base 1 is low and may be, for the purpose of illustration only, approximately 2%. The first and second turns of the coil at 3 and 4 represent the month of January and the twelfth and thirteenth turns of the coil represent December. In accordance with practice, the days of the month appear by numbers such as 1, 2, 3, 4, etc. which are not crowded together but are spaced apart. Thus the numbers will continue to the second turn 4 of the coil as shown. Each turn of the coil has an upper rim member 5 and a lower rim member 6 with an interposed helical slot 7. The upper and lower rim members of each coil turn are of rectangular section and the long side of a section is parallel to the axis of the helical coil. Thus, if all of the turns of the coil are considered together, the latral surfaces of each turn of the coil would form the lateral surface of a cylinder. Considering the first turn 3, the word January appears on rim member 6, as shown at 10. The word may be imprinted within the rim member or it may be of raised letter character. Between the lower edge 11 of the top rim member 5 and the upper edge 12 ice of the lower rim member 6 and within the slot or space 7 are spaced figures representative of the days of the month, as best shown in FIGURE 3 at 13 and 14. These figures may be molded to the upper and lower rim members 5 and 6 so that the figures at all times maintain a given position without shifting. Within the slot or space 7 and secured to the lower rim member 6, is a nob 15 and adjacent the nob is the numeral 1 representative of the first day of January and so on within the slot or space 7 and extending around the turn 3 and terminating with the numeral 31 representative of the 31st day of January on turn 4. Thus the numerals for the month of January include two turns 3 and 4 of the coil and subtend 360 as shown in FIGURE 1. A nob 16 projects from the inner edge of the lower rim member 6 into the space or slot 7 as shown at 16a and separates the numeral 31 of the month of January from the number 1 representing the first day of February. The numerals representative of the days of the month of February extend around the turn 4 into turn 4a terminating at point 17 which may be representative of either the 28th day or in some instance the 29th day, to represent a leap year. As before, the last number is separated by a nob 18 from the numeral 1 representative of the first day of the month of March. This procedure continues throughout the remaining turns of the coil to cover the twelve months, there being a nob between each month and the last and first days thereof. *Purposely the numbered divisions between two turns of a coil approximates thirty spaces as shown in FIGURE 2. Hence, the first day of each month and the fifteenth day thereof are diametrically opposite on the turns of the coil. In turn 3 of the coil it will be observed that a star is provided at 19 in space 7 to maintain the upper and lower rims apart and the same construction is followed for the December month turn 20 as shown at 21. The turn 20 terminates, as shown in FIGURE 7 with an enlarged star 22 joined to the upper and lower rim members at the end of the turn 20, as shown in FIGURE 7.

A day indicator or marker 30 is adapted for slide movement in the space 31 between adjacent turns of the coil. In FIGURE 1 it is to be observed that this space 31 lies between the upper rim 5 of one coil and the lower rim 6 of an adjacent coil. The day indicator or marker 30 has an arcuate web 32 and the rear face of said web is provided with a pair of flanges 33 and 34 in right angular relationship to the web. The flanges are adapted to be received in the space 31 between turns of the coil and the web overlaps the bottom rim member of one coil and the upper rim member of an adjacent coil as shown in FIGURE 6 at 35 and 36. The curvature of the indicator or marker member 30 corresponds to the curvature of the turns of the coil 2. The web on its external surface is provided with letters 39 indicative of the days of the week, as shown in FIGURES 4 and 6, these letters preferably having the same spacing therebetween as the spacing for the numbers representative of the days of the month, and which letters are raised or projected slightly beyond the normal surface 37 of the web as shown at 38. It is to be observed that the letters 39 are adjacent the lower edge 40 of the day indicator or marker. The degree of are covered by the indicator or marker 30 may vary although as shown in FIGURE 5, fourteen letters are carried by the marker. The letters 39 by *being adjacent the lower edge of the marker positions said letters adjacent the numbers representative of the days of the month, as shown in FIGURES 1 and 3. This is true particularly in view of the fact that the marker overlaps the top rim member 5 and a portion of the lower rim member 6 to position the letters adjacent the tops of the numbers representative of the days of the month with the result that there is no confusion in reading the calendar as to dates and days. The finger is adapted to engage the marker 30 and to slide the same within the space included between adjacent turns of the coil.

The operation, uses and advantages of my invention are as follows.

The calendar of the present invention may be of any size desired such as the size shown in FIGURE 1, and makes a convenient or interesting desk ornament with the base 1 of frusto-conical cross section upon the external surface of which may appear advertising matter or the name of the donor if the calendar is to be used for advertising purposes. The structure lends itself readily to casting. Thus the turns of the coil by having upper and lower rim members of varying width and spaced apart, as shown in FIGURES 1 and 3, permits the numbers of the month to be integrally formed with the upper and lower rim members in the space therebetween. This stabilizes the turns of the coil and by providing an indicator or marker bearing letters representative of days of the week the marker is easily moved between adjacent turns of the coil. The marker or indicator may be colored if desired to render the same distinguishable and, in fact, the turns of the coil may likewise be colored, if desired. Thus, the calendar may be given an ornamental and pleasing appearance. If desired, the base may be of solid construction to lend weight to prevent any tipping of the coil or it may be of annular form, as desired.

A calendar comprising: a helical coil having a space between each turn thereof and an indicator member interposed in the space between the coils and bearing notations representative of the days of the week; each turn of the coil bearing numbers representative of days of the month, the numbers being spaced apart the same distance as the spacing for the days of the month on the indicator member, and the indicator member having the same degree of curvature as the helical coil.
